DETAILED DESCRIPTION
[0024] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.

[0026] See attached Figure 1 The liner 100 is installed in the ball mill and is used to grind the ore to protect the inner wall of the ball mill. The liner 100 is arc-shaped as a whole, including a concave installation side 110 and a convex grinding side 120.
[0027] The liner 100 as a whole needs to be heat treated to improve the overall mechanical properties; after being heated in a heating furnace, the liner 100 is placed in a cooling tank for cooling. The traditional cooling process stacks multiple liner plates 100 and places them under the liquid surface of the cooling tank for cooling. Specifically, the liner plates 100 stacked in a receiving frame are placed under the liquid surface of the cooling tank for cooling by a crane. The concentrated liner plates are pressed against each other, resulting in some liner plates being unable to fully contact the coolant and unable to be completely cooled.
[0028] Some heat treatment equipment will lay the liner 100 flat on the surface of the platform, so that the heating conditions of the liner in the furnace tend to be consistent, and the state of the cold zone in the cooling tank also tends to be consistent, so as to ensure the uniformity of the temperature of the liner workpiece during heating, quenching and liquid discharge, which is beneficial to ensure the excellent mechanical properties of the liner; however, the area occupied by each of the flat liner 100 is large, and the number of liner 100 heated and cooled at one time is limited, so the heating and cooling efficiency of the liner 100 is limited.
[0029] In order to solve the above problems, refer to the attached Figure 2 -Attached Figure 6A heat treatment equipment for lining plate processing includes a bearing platform 200 for bearing a lining plate 100. The surface of the bearing platform 200 is provided with a plurality of bearing openings 210 which pass through from top to bottom. The bearing platform 200 also includes a limiting device 300 for positioning the lining plate 100. The limiting device 300 can limit the lining plate 100 so that the lining plate 100 can be separated and placed in a vertical state. Adjacent lining plates 100 are arranged at intervals. Each lining plate 100 can be fully in contact with the coolant, thereby ensuring the cooling efficiency of each lining plate 100. At the same time, the bottom area of the vertically placed lining plate 100 is small. When the area of the bearing platform 200 is the same, the number of lining plates 100 placed at a single time is greatly increased, thereby greatly improving the efficiency of heating and cooling the lining plate 100 at a single time.
[0030] Specifically, the limiting device 300 includes a first limiting component 310 located on both sides of the bearing platform 200, and a plurality of second limiting components 330 located between the two first limiting components 310. The second limiting components 330 are alternately arranged with the bearing opening 210. A plurality of limiting chambers are formed between the two first limiting components 310 and the plurality of second limiting components 330. The liner 100 is separated and placed in a vertical state through the limiting chamber. When the liner 100 is in a vertical state, the bottom is in a state of being limited by the bearing opening 210. The installation side 110 and the grinding side 120 are respectively limited by the corresponding first limiting components 310 and the second limiting components 330, so as to ensure that the liner 100 is in a vertical state in the limiting chamber. Adjacent liner plates 100 are separated by the second limiting components 330, and a flow channel for the coolant to pass through can be formed between adjacent liner plates 100, so as to ensure that the liner plate 100 can be fully cooled in all directions, thereby improving the heating and cooling efficiency of the liner plate 100.
[0031] It should be noted here that the limiting device 300 here is made of high-temperature resistant rigid material, and its high-temperature resistance performance is higher than that of the heat-treated lining 100. The whole can enter the heating furnace for heating along with the lining 100, and the whole structure enters the cooling tank for cooling after heating. Before the lining 100 is heat-treated, the lining 100 is placed in the limiting chamber in sequence, and the lining 100 remains stable in the limiting chamber.
[0032] The first limiting component 310 includes a limiting column fixed to the supporting platform 200, and a first limiting protrusion 311 is fixed to the side wall of the limiting column. The first limiting components 310 located on both sides have a larger cross-sectional size and are located on both sides to play a supporting and limiting role. At the same time, by setting the first limiting protrusion 311, the contact area with the liner 100 at the edge can be reduced, so as to increase the contact area between the liner 100 on both sides and the cooling liquid, and further improve the cooling effect of the coolant.
[0033] The cross-section of the load-bearing opening 210 here is an inverted trapezoid. The size of the bottom of the load-bearing opening 210 is smaller than the size of the bottom of the liner 100, which can restrict the liner 100; the bottom opening of the load-bearing opening 210 is smaller than the top opening, which can limit the liners 100 of different sizes; the coolant can flow in from the load-bearing opening 210 to cool the top liner 100.
[0034] A second limiting protrusion 211 is fixed on the side wall of the load-bearing opening 210. The second limiting protrusion 211 is located near the bottom of the load-bearing opening 210 and can support the lining plate 100, increase the supporting area of the lining plate 100, reduce the pressure on the bottom of the lining plate 100, ensure the supporting stability of the lining plate 100, and avoid bottom deformation.
[0035] The second limiting assembly 330 here includes a mounting sleeve 331, and a limiting rod 332 detachably connected to the mounting sleeve 331. The limiting rod 332 can be plugged in and out of the mounting sleeve 331. The limiting rod 332 is tightly pressed against the lining plates 100 on both sides. Both sides of the lining plates 100 are squeezed by the lining plates 100 at different positions, and the forces on both sides cancel each other out. The limiting rod 332 here mainly plays a separating role, so that the adjacent lining plates 100 in different limiting chambers can be separated from each other, ensuring that the lining plates 100 in adjacent limiting chambers can be fully cooled. The mounting sleeve 331 and the limiting rod 332 array here are arranged in multiple groups to ensure the stability of the load-bearing support.
[0036] Furthermore, the limiting chamber separates and places the two liner plates 100 in a vertical state, and the two liner plates 100 located in the same limiting chamber are symmetrically arranged, and the grinding sides 120 of the two liner plates 100 are in contact with each other. Figure 6 Adjacent limiting chambers are limited by a second limiting assembly 330. Through the above-mentioned structural design, the accommodating number of the limiting chambers can be further increased, and the lining plate 100 can be placed more neatly in the limiting chambers.
[0037] A third limiting assembly 320 located between the two adjacent liner plates 100 is provided on the top of the two liner plates 100. The third limiting assembly 320 can separate the two adjacent liner plates 100 located in the same limiting chamber, so that the liner plates 100 in the same limiting chamber, specifically the grinding side 120 of the liner plates 100, can fully contact with the coolant to ensure the cooling effect; the third limiting assembly 320 here can be selected as a high temperature resistant limiting block, which is manually placed at the top position of the two liner plates 100 during the initial placement of the liner plates 100; the two sides of the liner plates 100 are effectively limited, and the position state is stable during heating and cooling.
[0038] Symmetrically arranged lifting ears 400 are installed on the upper surface of the carrying platform 200, and a suspension device such as a crane can be connected through the lifting ears 400, so that the whole structure can be quickly suspended from the heating furnace to the cooling tank to achieve automatic cooling.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
